FiberForce T1

FiberForce T1TM is a cold-drawn steel wire fiber developed for use as temperature-shrinkage reinforcement and post-first crack toughness in concrete, increase load carrying capacity of slabs-on-ground.

This product is also available in various lengths: FiberForce T1-50 (50 mm) and FiberForce T1-60 (60 mm).


  • Light, Medium, Heavy Industrial, and Commercial Slabs-on-Ground
  • Blast Resistant Structures
  • Truck Access Pavements (Malls, Industrial and Warehouse sites)
  • Heavy Duty Pavements (Airports and Highways)
  • Precast
  • Tunnels and Mines

Recommendations for Use

Recommended dosage rate is between, but not limited to, 25 – 120 lbs. per cubic yard.

However, a specific dosage rate should be established by the project engineer or government agency for a given application based on project conditions and requirements.

FiberForce T1 is not intended to replace primary, structural steel in concrete.

Mixing Instructions

The steel fibers are pre-packaged in bags or boxes that are NOT water-soluble, hence the fibers must be removed from its packaging for use.

To ensure optimum distribution, the fibers must be added to the ready-mix drum after the conventional concrete ingredients have been properly mixed.

The fibers must be introduced at a constant/uniform rate while the drum is revolving at mixing speed.

A minimum of 75-100 revolutions at mixing speed or 5-7 minutes of mixing at high speed may be needed to ensure complete dispersion of the fibers.

For detailed mixing, placing and finishing instructions, please contact your Regional FiberForce Expert.

Features & Benefits

  • Provides post-first crack residual strength to concrete
  • Provides temperature-shrinkage reinforcement
  • Increases concrete durability - including impact and abrasion resistance and fatigue strength
  • Provides uniformly distributed reinforcement throughout the concrete, not just in one plane as with traditional steel reinforcement
  • A cost-effective alternative to traditional steel reinforcement
  • Temperature-shrinkage reinforcement in composite metal deck systems
